Low volume when connecting a Sound Bar to a TV via HDMI or optical

When you use an external cable tuner, satellite box, set-top box, or other sound sources with an independent volume control, you might notice a difference in volume between this external tuner and other sources that are connected to the TV or Sound Bar.

The easiest way to achieve a comfortable volume level is to set the volume of an external source to the maximum level and adjust the TV or Sound Bar volume according to your preference.
